The modern solution for fixing stair treads.
Anyone planning a wooden or steel stringer staircase will, sooner or later, be faced with the question: How can stair treads be fixed in place so that they are durable, stable and as simple as possible?
Stair tread supports offer a modern alternative to traditional staircase designs. They enable the stair treads to be fitted with precision, reduce the amount of work involved in manufacturing, and at the same time create a high-quality finish.
Whether in professional staircase construction, metalwork or private staircase projects – stair tread supports have proven to be an efficient solution for securing stair treads.

What are stair stringers?
Stair tread supports are specialised fasteners used to secure stair treads to timber or steel structures.
They act as a stable bearing surface between the supporting structure and the step, providing a secure, durable and easy-to-install connection.
Depending on the staircase design, step supports are used, for example, in the following types of staircase:
- Wooden stringer staircases
- Steel-stringer staircases
- Designer staircases
- Stringer staircases
- Custom designs
- Staircase renovations
- Direct wall mounting
The benefits of stair landings at a glance
Simple and quick assembly
Step supports allow stair treads to be positioned and secured with precision. This significantly reduces the amount of installation work required, saving time both in the workshop and on site.
Less milling work
Many traditional staircase designs require complex milling or recesses. Step supports allow for a much simpler design and reduce the amount of machining required.
Replaceable stair treads
A major advantage of modern stair tread supports is that individual treads can be replaced as and when necessary. Damaged or worn treads do not have to be laboriously removed from the entire structure.
High-quality, exposed construction
Our stair stringers are deliberately designed to be a visible design feature. Rather than using concealed fixings, this creates a technically and visually high-quality staircase solution with clean, modern lines.
The combination of precision metalwork and an exposed structure gives the staircase an industrial, modern character and highlights the quality of the overall finish.
In this way, the stair tread fixings are not concealed, but are deliberately incorporated as part of the design – functional, sturdy and visually appealing.
A permanently stable connection
High-quality stair tread supports ensure a secure connection between the stair tread and the supporting structure and are designed for long-term use.
Why staircase builders rely on stair tread supports
Many staircase builders, metalworkers and joiners are looking for solutions that simplify the manufacturing process whilst ensuring a high standard of quality.
Step supports offer precisely these advantages:
- Shorter installation times
- Precise positioning of the steps
- Clean designs
- Low-maintenance solutions
- A professional appearance
- Versatile applications
Particularly in the case of bespoke staircase projects, stair tread supports often offer greater design flexibility than traditional fixing methods.

Versatile in use

Suitable for wooden-stringer staircases
In the case of timber stringer staircases, step supports enable the steps to be securely fixed in place without the need for complex traditional constructions. The steps can be fitted with precision and, if necessary, replaced at a later date. At the same time, the natural appearance of the timber structure is preserved.

Suitable for steel stringer staircases
Step supports have also proved their worth in steel-stringer staircases. They enable wooden steps to be securely attached to a steel structure and create a high-quality combination of modern design and functional stability.

Suitable for direct wall mounting
Our stair tread supports are also used successfully for the direct wall mounting of stair treads. They enable wooden treads to be secured safely and precisely directly to the wall, creating a stable structure for modern, seemingly floating staircase solutions that offer a high degree of design freedom.

Developed from real-world experience
The products in the Ammann Stepstore were not designed on the drawing board, but were developed in response to the practical demands of day-to-day staircase construction.
The experience gained from numerous staircase projects was directly incorporated into the development of the stair tread supports. The result is a range of well-designed solutions for the professional installation of stair treads.
